- Abstract
- Densities and viscosities of ternary systems comprising of water + propan-2-ol and an electrolyte have been measured at different solvent compositions and electrolyte concentrations at temperatures between (288.15 and 313.15) K. The electrolytes employed were LiCl, NaCl, KCl, KI and SrCl2 most of which are either commonly found in natural water or have industrial applications. The concentrations of the electrolytes in various mixtures were increased to almost saturation and have been expressed in the temperature-independent molality (m) scale. Linear variation of densities with m can be expressed in terms of the gradient (the so-called g-factor) for different mixture compositions and the electrolytes. Viscosities of solutions have been explained using polynomials in m). With the exception of KI, for all the other electrolytes two immiscible phases are formed at the maximum working concentrations in the solvent mixtures having water mole fraction of 0.8.
